NOTICE
Danger of unintentional movement of hoist
If the rocker switch is no longer depressed by the operator, it returns to the 0 position,
the hoist motion is automatically stopped (dead man’s
control).
If the hoist malfunctions, e.g. the actual motion does not correspond to the motion
intended in activating the rocker switch, release the rocker switch immediately. If the
motion continues, press the emergency stop button.
If this also fails to bring the hoist to a standstill, the emergency stop switch (mains
connection switch) should be immediately switched off and secured to prevent re-
activation.

WARNING
Danger of bodily injury
After an emergency stop, the operator must not restart the hoist /crane system until a
qualified person has determined that the fault which led to this function being activated
has been eliminated and no danger can arise from the continued operation of the system.
Every hoist must have a means of disconnecting the power supply to all drives under load
from the ground.
